In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Water, Water Everywhere
Source Institutions
In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
Super Soaker
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
Use Clues to Solve an Ice Mystery
Source Institutions
Learners explore the variables that affect the properties of ice and the places where different types of ice are found.
Stuck on You: Adhesion
Source Institutions
Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.
Crumple a Watershed
Source Institutions
Learners gain an intuitive knowledge of the physical aspects of watersheds by creating their own watershed models.
Global Climate Change and Sea Level Rise
Source Institutions
In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
